Latent And Sensible Energy Reduction For Outside Air

Innovent LASER Packaged Fresh Air Conditioning Units

Innovent LASER units provide both sensible and latent control of outside air at greatly reduced energy costs compared to conventional systems.

Benefits of LASER Technology Innovent offers a ■ Energy costs are reduced using the Innovent heat exchanger to provide “free” precooling and reheat. simple, economical ■ Tempered outside air is provided at low relative humidity. solution to the challenge of meeting ■ Outside air volume is constant and verifiable. the ASHRAE design standard for more ■ Heating/Cooling equipment is selected based on the room load only, reducing the size of the equipment fresh air. and associated duct systems.

■ Humidity in duct work is lower than that for typical cooling equipment. This helps prevent bacteria growth in duct insulation.

LASER-1 units are designed to condition and deliver fresh air to either the space or the intake of a conventional air handler. LASER-2 units have an exhaust air blower and additional heat exchanger for energy recovery from the exhaust airstream.

Both LASER-1 and LASER-2 designs have been pre-engineered over a wide range of airflows. Each unit is designed to incorporate DX or chilled water cooling and a wide variety of heating and filtration options. DX units are available with integral packaged air cooled and water cooled condensing units.

Heating Options Cooling Options Hot Water Coil Chilled Water Coil Steam Coil DX Coil, Split System Indirect Fired Gas Air Cooled DX Coil Electric Heater Water Cooled DX Coil Direct Fired Gas Water Source Heat Pump

All units are fully wired for single point connection and are ETL listed. 24393_4.qx5 8/10/05 9:24 AM Page 3

Designed For High Performance And Low Maintenance

Innovent LASER — Engineered Simplicity in Operation and Maintenance

Innovent products are designed to give long term high performance and low maintenance. The LASER product line continues that tradition.

Over half a decade ago, Innovent realized the necessity for double wall construction in our energy recovery air handlers. Although the market at that time was predominantly single wall, Innovent made the commitment to double wall construction. It is now the industry standard.

Double Wall Construction Provides: ■ Protection for insulation

■ Long unit life

■ Cleanable interior

Innovent Double Wall with Full Independent Frame provides: ■ Total maintenance access

■ Modular design flexibility for retrofit

■ Superior structural design

■ Quiet operation

■ Longer unit life

Many double wall units offered today are modified single wall units with a “liner” covering the insulation. These designs sacrifice maintenance access and structural integrity. Innovent LASER units are built with a full independent frame, flush mounted double wall casing, and fully hinged access doors.

Engineered Simplicity in Heat Exchanger Design. Innovent’s exchanger is the least likely to foul, and the easiest to inspect and clean in the industry.

■ Innovent’s LASER heat exchanger design HAS: - Lower pressure drops

- Simple airflow pattern, 100% accessible surface

■ Innovent’s LASER heat exchanger design does NOT have: - Speed controls, motor/drive sets

- Refrigerants, secondary surface, high fin density

- Dimples, corrugations, baffles 24393_4.qx5 8/10/05 9:24 AM Page 4
